Description

CPC–104P is a PCI-104 plug-in card for the CAN bus. Designed for industrial series
applications CPC-104P has a robust and cost efficient layout. CPC–104P supports up to
four CAN controller of type NXP SJA1000.
CPC-104P maps the CAN controller into the PC address space and thus allows access to
CAN messages with low latency. Existing software for the supported CAN controller can
easily be adapted. With CPC-104P the CAN communication may be handled either in
interrupt controlled or in polled mode.
CPC-104P can optionally be delivered with galvanic decoupling of the CAN bus. The dual
and quad channel versions have the additional option of galvanic decoupling between CAN
channels.
